need作情态动词时，它具备情态动词的所有特点：没有人称和数的变化，后面直接加动词原形，后面直接加not构成否定，提前构成疑问句。如：He need read more books. He needn't finish it today. Need he do it?
need作实义动词时，它具备实义动词的所有特点：有人称和数的变化，借助于助动词dot构成否定，疑问句。如：He needs to read more books. He doesn't need to finish it today. Does he need to do it?
另外，need作实义动词时，可以构成词组： need sth need to do sth need sb to do sth
